Carbon dating explained simple

After a creature's death the isotope would slowly decay away over millennia at a fixed rate.

Thus the less of it that remained in an object, in proportion to normal carbon, the older the object was.

Making the job harder still, baffling anomalies turned up.

The carbon-14 dates published by different researchers could not be reconciled, leading to confusion and prolonged controversy.

Any contamination of a sample by outside carbon (even from the researcher's fingerprints) had to be fanatically excluded, of course, but that was only the beginning.

Delicate operations were needed to extract a microscopic sample and process it.

To get a mass large enough to handle, you needed to embed your sample in another substance, a "carrier." At first acetylene was used, but some workers ruefully noted that the gas was "never entirely free from explosion, as we know from experience."(4) Ways were found to use carbon dioxide instead.

Nuclear laboratories, awash with funds and prestige, spun off the discovery of an amazing new technique — radiocarbon dating.This was all the usual sort of laboratory problem-solving, a matter of sorting out difficulties by studying one or another detail systematically for months.More unusual was the need to collaborate with all sorts of people around the world, to gather organic materials for dating.A stronger field would tend to shield the planet from particles from the Sun, diverting them before they could reach the atmosphere to create carbon-14.and "not very attractive."(8) However, solar specialists knew that the number of particles shot out by the Sun varies with the eleven-year cycle of sunspots.
